Abstract:
A power reception device transmits authentication information (e.g., start code, manufacturer ID, product ID, rated power information, and resonance characteristic information) to a power transmission device before starting normal power transmission by a non-contact power transmission system. The power transmission device performs instrument authentication based on the received authentication information, and regulates the maximum transmission power is regulated to conform to a power-reception-device side rated power. The power transmission device then performs normal power transmission.
